The correct answer is D. A concrete example is one that provides a clear situation in which the abstract idea, in this case the author's argument, is exemplified. This option not only prepares the reader for the example, but also gives specific details about what could be regulated.
Well, firstly, I need to see the essay but in my opinion from what you are saying I think that the title is something to do with the story. So, "Cinderella, the Legend" so, it might be a Legend. It doesn't say The Great Cinderella or something which means the author has a normal feeling about it and doesn't think it's good neithier bad so, the author has a neutral feeling about Cinderella. I hope this helps! ^^
